尼日利亚采购需求：充电宝

I'm looking for a high-capacity power bank that can deliver 22.5W with multiple outputs. The desired specs include a total capacity of 30000mAh, built with three 10000mAh batteries for optimal performance. The dimensions should be compact, ideally around 150mm in length, 67.6mm in width, and 42.2mm in height, keeping the weight manageable at about 686g. The design should feature a sleek metallic gray finish. For the input options, I'd like both micro and Type-C ports that support various voltage and amperage options. The outputs should include two USB ports with the ability to handle multiple voltage levels (4.5V to 12V) at varying currents, along with a Type-C output that can provide efficient charging capabilities. Please confirm availability and pricing details for this product, along with any customization options you may offer.
